Henri Lamiraux, Apple’s top Vice President of Engineering for the iOS iPhone, iPad, and iPod touch operating system has left the company, according to a source and corroborated by his LinkedIn profile.

Lamiraux confirmed his departure to me via email. He says that he retired from Apple a “couple of weeks” ago, following the release of iOS 7.0.3. Lamiraux decided a “little while ago” that iOS 7 would be his last release…

Since Apple announced late last month that longtime iOS chief Scott Forstall and newly appointed head of retail John Browett would soon leave the company, there has been much talk about CEO Tim Cook’s direction at the executive level going forward.

The departure of Forstall saw bigger responsibilities and new roles given to executives Craig Federighi, Bob Mansfield, and Jony Ive, leading to rumors Forstall didn’t see eye to eye with the other executives. Bob Mansfield’s return after announcing retirement is also interesting, as it is something new sources said was directly influenced by Forstall leaving. Some even said Forstall’s refusal to sign the Maps apology lead to Cook’s decision. There are a few in-depth reports today, with many citing people close to the company, speculating on what these changes might actually mean for the company and for iOS in the months and years to come.

AllThingsD is out with a new report, claiming Mansfield’s return might have been directly influenced by Forstall’s departure:

Sources said that Mansfield was actually very serious about retiring, which makes his quick return to Apple all the more curious… As one source close to the company told AllThingsD, “The timing of Bob’s return is notcoincidental.” To begin, Mansfield was not a fan of Forstall’s confrontational management style, and sources said he generally tried to avoid the iOS exec.

“It wasn’t a him-or-me situation,” one source said of Mansfield’s return and Forstall’s ouster. “But, put it this way, I think Bob was much more willing to commit to two more years once he knew Scott was on his way out.”

Many of the reports speculated Jony Ive’s new role picking up Forstall’s Human Interface responsibilities would lead to major changes in iOS’ visual design:
